IMPROVEMENT IN MdVABLEHEAD-LIGHTS.

Specification forming part of Letters Patent No. 150,457, dated May 5,1874; application filed February 21, 1874.

To all whom it may concern:

Be it known that I, HoRATIo G. ANGLE, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inMovable Head-Lights, of

which the following is aspecification:

Figure l is a side view of my improved de vice, shown as applied to alocomotive, the truck being shown in section. Fig. 2 is a top View ofthe same. Fig. 3 is a detail section taken through the line 00 00, Fig.1.

Similar letters of reference indicate corresponding parts.

The invention'will first be fully described, and then pointed outin theclaim.

A represents a locomotive-engine, about the construction of which thereis nothing new. To the front of the locomotive is attached the shelf B,upon which the head-light G stands, and to which it is secured by abolt, D, which also serves as a pivot to said head-light. To the bottomof the head-light O, in front of the. pivoting-bolt D, is attached a pinor. eyebolt, E, which passes down through a curved slot inthe shelf B,and with its lower end is connected a crank'arm, f formed upon the upperend of the vertical rod F,-which works in bearings attached to the frontof the engine A. Upon the lower end of the rod F is formed a crank-arm,f which passes between the forks of a slotted arm, G, attached to thetruck-frame of the engine. With this construction, as the truck turns inpassing around a curve, the head-light O is also turned, so that thestream of light may always be thrown upon the track. By lengthening orshorten ing either of the crank-arms f f the light from the lamp may bethrown more or less from a straight line to adapt it to the curvaturesof the road. To one side of the headlight 0 is rigidly attached a shortarm, H, to the outer end of which is pivoted the forward end of a rod,I, which passes back along the top of the engine, so that it may bereadily reached and operated by the engineer. The devices H I enable theengineer to turn the head-light a little farther or not so far as itwould be turned automatically by the truck, to guide the stream of lightas may be desired, the elasticity of the rod F allowing it to be twistedsufficiently for the purpose. The automatic feature need not be used, inwhich case the head-light is operated by, and is under the full controlof, the engineer by means of the rod I and arm H. With some engines theupper crank-arm f of the rod F need not be used.' In some cases, also,the head-light may stand over the pivotal center of the truckframe, inwhich case the cranks upon both ends of the rod F might be dispensedwith and the same results obtained.

Havin thus described my invention, I claim as new and desire to secureby Letters Patcut- The combination, on a locomotive, in the mannerdescribed, of a slotted shelf, B, a rod, F, having crank-arms f f andthe slotted arm G on the truck-frame.
